The ergosterol pathway in fungal pathogens is an attractive antimicrobial target because it is unique from the major sterol (cholesterol) producing pathway in humans. Lanosterol 14alpha-demethylase is the target for a major class of antifungals, the azoles. In this study we have isolated the gene for this enzyme from Cryptococcus neoformans.

Widespread use of fluconazole has resulted in resistance in strains of Candida. The aim of our study was to investigate Y132H and other mutations in the ERG11 gene in conferring fluconazole resistance to C. albicans isolates. Seven fluconazole-resistant (R)/susceptible dose-dependent (SDD)/trailing and 10 fluconazole-susceptible (S) isolates were ...

Azole resistance in the pathogenic yeast Candida albicans poses significant challenges for its antibiotic treatment. The conformational change of the target enzyme 14 alpha-demethylase (Erg11p) due to ERG11 gene mutations is one of the mechanisms resulting in the azole resistance.

We investigated the susceptibility of Candida albicans isolated from clinic specimens to azole antifungal agents and estimated the association of the ERG11 mutations with azole resistance during recent 5years in China. In this study, novel mutations G346A, A434V, and L480F in ERG11 may be related to azole resistance in C. albicans.

Upregulation of the ERG11 gene in Candida krusei by azoles.
Daru : journal of Faculty of Pharmacy, Tehran University of Medical Sciences, 2012Candida species are the agents of local and systemic opportunistic infections and have become a major cause of morbidity and mortality in the last few decades. Azole resistance in Candida krusei (C. krusei) species appears to be the result of gene alterations in relation to the ergosterol biosynthesis pathway, as well as efflux pumps.

The molecular mechanisms underlying fluconazole resistance in C. albicans involve mutations and the overexpression of the ERG11 gene and membrane transport proteins. We examined the relationship between the reduced fluconazole susceptibility of C. albicans and mutations of V404I and V509M in the ERG11 gene in 182 C. albicans clinical isolates using the

[Analysis of ERG11 gene mutation in Candida albicans].
Di 1 jun yi da xue xue bao = Academic journal of the first medical college of PLA, 2007To study the relationship between fluconazole (FCZ)-resistance of Candida albicans and the mutation of ERG11 gene encoding FCZ-targeted enzyme.Three strains of FCZ-susceptible and 10 FCZ-resistent C. albicans were isolated from the urethra, vagina, oropharynx, respiratory tract, prostate secretion and blood samples.

Farnesol (FAR) has already demonstrated an inhibitory effect on Candida albicans biofilm. The aim of this work was to determine the effectiveness of externally added FAR in combination with fluconazole (FLC) on Candida albicans biofilm and on regulation of the ergosterol genes ERG20, ERG9, and ERG11. The effectiveness of compounds was determined by MTT

Variation in the erg11 Gene from Pneumocystis jirovecii.
2010The erg11 gene codes for sterol 14-demethylase (14DM), a key enzyme in sterol biosynthesis and the target for triazole antimycotic drugs. Two sterol composition phenotypes have been described in patients with pneumonia caused by P. jirovecii; one phenotype has a much higher amount of lanosterol derivatives (C31 and C32 sterols) dominated by ...

The steep increase in acquired drug resistance in Candida isolates has posed a great challenge in the clinical management of candidiasis globally. Information of genes and codon sites that are positively selected during evolution can provide insights into the mechanisms driving antifungal resistance in Candida.
